Application filed July 11- 1907. Serial No. 383.287.

To all whom it mayroncem. Be it known that l, Airs Svnxssox 136K, a

7 subject of the King of Sweden, and resident This invention relates to improvements in journaling devices for rotating and rocking shafts and more especially to an'improved supporting and coupling device for such The object of the invention is to reduce to a minimum the resistances caused by the deviations between the rocking shaft and the member supporting the same. i

The invention consists, chiefly, in the combination in a journaling device for rocking shafts, of a rocking bearing-body, a nonroching-supporting member, and a shaft in said bearing-body resting on said su porting member in or near to a point coincir ing with the rocking center of said bearingdmdy.

In the accompanying drawing forming a specification Figures 1 and 2 show each an embodiment of my invention in vertical section.

Referring to Fig. 1, the pin 2 of the shaft 1 is journaled in an elastically articulated bearing-body 3. At the lower end the pin 2 has a center {1 resting on the upper end of a supporting member constituted by a pin 6 screwed into the part 0f the frame 11. The center of the s herical rocking surface 7 of the bearing-b0 y 3 coincides with the point Where the dotted line ab-crosses the axis of r the pin 6, and said point is also the centerof the upper spherical; supporting surface of the pin 6. The bearing body is provided with a flan 'e' 8 which is loaded by a spring 9, the tension. of which is cont-rolled by means of a ring-nut 1O screwed into the frame 11. It is obvious that the rocking movements of'the bearing body caused by the shaft 1 and the spring'l) cannot cause any transversal pressures on the bearing-surfaces emanating from thesupporting and rocking center.

rReferring to Fig. 2 and 11 indicate same or corresponding parts as the same reference numerals in Fig. 1, the upper hollow part of the pin 2 incloses the conical part 12 of. the shaft 1 the lower end of which is-formed as an edge 13 by means of which the shaft in the usual manner is caused to partake in the rotation of the pin 2. The lower end of. the latter is double- 'n which 1, 2, 3, 7, 8,

forked, and each of the forks engages one of two pins 15 in alinement with each other,

said pins being integral with and forming a cross together with two other pins 16 right'angles to the pins 15. The pins 16 are engaged by the uppermost double-forked. part 21of a supporting shaft 17 journaled in a removable bushing 18 in the frame 11. driving power-"is transferred to the shaft 1 by means ofthe shaft 17, the cross 15, 16 and the pin 2. In as much as the axes of the pins 15 and 16 cross each other in or near to the center of the spherical rocking surface 7 of the bearing body 3, it is obvious that also here the rocking movements of the shaft 1 and the bearing-body cannot'cause any transversal pressures between the rotating supporting and supported parts.

Instead of the spiral spring 9 shown in Fig. 1 ring-shaped conical spring-plates 19 are used, the tension of whichis controlled by means of the ring-nut 1O screwed into a removable bushing 20 inscri ed in the frame 11.

Having now described my invention what I claim as new and desire to secure by Letters Patent is:

1, In a journaling device for rotating and rocking shafts, the combination of a non rocking supporting member, a body bearing and arranged to rock in said' member, a shaft disposed in and arranged to rock with said bearing bod ,and means independent of the bearing bo y, for supporting said shaft in the bearing body; said means being arranged within the bearing body and in the center of the rocking movement thereof.

2. In a journaling device for rotating and rocking shafts, the combination of a nonrocking supporting member, a body bearing and arranged to rock in said member, a shaft disposed in and arranged to rock with said bearing body, means independent of the bearing body, for su porting said shaft,. in the bearing body; said means being arranged within the bearing body and in the center of the rocking movement thereof, audit s )ring arranged between an abutment on the ear. ing body and an abutment on the non-roclo .ing member, disposed above the first men tioned abutment.

3. In a journaling device for rotating and rocking shafts, the combination of a nonrocking supporting member, a body bearing and arranged to rock in said member, a shaft disposed in and arranged to rock with said bearing body, means supporting said The shaft, arranged within the bearing body and in the center of the rocking movement thereof, a ring adjustable vertically in the nonrocking supporting member, and a spring arranged between said ring and an abutment on the bearing body, located below the ring. I

4. In a journaling device for rotating and rocking shafts, the combination of a nonrocking supporting member, a body 'bearin and arranged to rock in said member an having an exterior flange, a shaft disposed in and arranged to rock with said bearing body, Within the bearlng body and in the center of able vertically means supporting said shaft, arranged NILS SVENSSON BOK.
